My new gamma is happily toiling away at just under 2 TH/s, but I wonder if I could break the 2 TH/s barrier if I had a better psu. Anyone tried this and/or have psu recommends?

Have you upgraded the fan, heatsink, etc on your bitaxe? Otherwise you will fry it with a larger psu lol.

@sunny-skies123 Yup it already came with a fairly robust heatsink and upgraded fan (noctua). It's running steady at 54c with 20 degree ambient and fan at 90%, so not shabby at all. Guess I'm just a lil greedy for hash and want to see how far I can push it haha. 🙃

I recommend a meanwell power supply. The one I use is https://www.amazon.com/Mean-LRS-350-5-Power-Supply-Signs/dp/B07PDTDKRY?ref_=ast_sto_dp&th=1

@tech-guru2025 Nice! Looks like it has plugs for 3 units but enough power for more? Could I, theoretically, connect more units if I splice? 🤔

@magicmike42 Hmm, I'd say yes but remember the power rating shown is always "peak" so you never wanna reach that. Rule of thumb is don't exceed 80% of capacity so... this one is 300w and the gammas consume 25 to 30w each.. I wouldn't stack more than 7 just to be abundantly safe. You technically could get away with 8, but not worth even the small risk IMHO.

@magicmike42 typically a meanwell 5v 300w on Amazon will be enough to run several bitaxes at once.
